Dolby Digital Plus will be supported by Windows 7 – it has been announced – offering high-quality multichannel audio.
Dolby Digital Plus is described as a "complete audio system that spans the whole gamut of sources – from internet content to HDTV and optical discs; providing 7.1 channels and bitstream".
The audio codec maintains the quality of Dolby Digital at a lower data rate – and is compatible with 'all current' Dolby Digital AV receivers.
